android数据绑定生成类错误：包不存在

Question

我将我的项目迁移到 androidx，代码没有错误，但是一旦我尝试重新构建项目，我在生成的类中收到以下错误。 app/build/generated/data_binding_base_class_source_out/debug/dataBindingGenBaseClassesDebug

error: package android.support.design.widget does not exist 
error: package androidx.appbarlayout.widget does not exist  
error: package androidx.collapsingtoolbarlayout.widget does not exist   
error: cannot find symbol class ViewPager   
error: cannot find symbol class AppBarLayout    
error: cannot find symbol class CollapsingToolbarLayout 
error: cannot find symbol class ViewPager   
error: cannot find symbol class TabLayout   
error: cannot find symbol class AppBarLayout    
error: cannot find symbol class CollapsingToolbarLayout 
error: cannot find symbol class ViewPager   
error: cannot find symbol class TabLayout

我检查了我的 gradle 文件，所有依赖项都更新为 androidx。 这是代码。

    implementation "com.github.hotchemi:permissionsdispatcher:${permissionsDispatcherVersion}"
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'

例子，

错误：包 androidx.appbarlayout.widget 不存在

您现在需要使用不同的库，即com.google.android.material.appbar.AppBarLayout 。

请在应用程序中找到被替换以支持 AndroidX 的类映射。
